Ataya : It's now PM2.5 season, Air pollution is on the peak rate in Thailand. So I just bought Smartmi PM2.5 monitor and I want to find the way to reduce PM2.5 in my room. The first way is to use electric fan to blow the wind at wet towel. I hope the wet towel can catch some PM2.5 particles. Let's see the result ...
Experimental condition :
- My room was sealed, all windows and door were closed.
- The room volume is about 4x4x3 cubicmeter.
- On one was in the room during 1 hour of the experiment.

| PM2.5 before fan On |
 |
| Just hang wet towel on electric fan and turn it on. |
 |
| PM2.5 after 1 hour |
As result : the PM2.5 was reduced by 43-37 = 6 milligram / cubicmeter
reduce rate = 6 / 60 = 0.1 milligram/cubicmeter/minute
efficiency rate =( 6 / 43) x 100 = 13.95 %
Hope this information can be helpful for everyone. Save the world save yourself !!
